On MILP modelisations
Orateur : Christina Boura (UVSQ, CNRS, LMV)
Modelizing a problem using linear constraints and solving it by some Mixed Integer Linear Programming (MILP) solver is a popular approach in many domains of computer science. In this talk we present and compare different new techniques to modelize any subset of {0,1}^n for MILP. We then discuss the efficiency of our models by applying them to the search of differential paths, a classical problem[…] -

An evaluation of Symbolic Execution Systems and the benefits of compilation with SymCC
Orateur : Aurélien Francillon (Eurecom)
In this talk I will discuss our recent work, together with Sebastian Poeplau, on Symbolic execution. Symbolic execution has become a popular technique for software testing and vulnerability detection, in particular, because it allows to generate test cases for difficult to reach program paths. However, a major impediment to practical symbolic execution is speed, especially when compared to near[…] -

Where ML Security Is Broken and How to Fix It
Orateur : Maura Pintor (PRA Lab, University of Cagliari)
To understand the sensitivity under attacks and to develop defense mechanisms, machine-learning model designers craft worst-case adversarial perturbations with gradient-descent optimization algorithms against the model under evaluation. However, many of the proposed defenses have been shown to provide a false sense of robustness due to failures of the attacks, rather than actual improvements in[…] -

Browser fingerprinting: past, present and possible future
Orateur : Pierre Laperdrix (CRIStAL)
Browser fingerprinting has grown a lot since its debut in 2010. By collecting specific information in the browser, one can learn a lot about a device and its configuration. It has been shown in previous studies that it can even be used to track users online, bypassing current tracking methods like cookies. In this presentation, we will look at how this technique works and present an overview of[…] -

Intrusion Detection Systems over an Encrypted Traffic: Problem and Solutions
Orateur : Sébastien Canard (Orange)
Privacy and data confidentiality are today at the heart of many discussions. But such data protection should not be done at the detriment of other security aspects. In the context of network traffic, intrusion detection system becomes in particular totally blind when the traffic is encrypted, making clients again vulnerable to known threats and attacks. Reconciling security and privacy is then one[…] -

Implémentations sécurisées et évaluation pré-silicium contre les attaques physiques.
Orateur : Sofiane Takarabt
Side-channel attacks remain a permanent threat against embedded systems, thus reliable protections should be implemented and must be minutely evaluated. In this presentation, we study different possible ways to evaluate against such threats. We show how an evaluation can be carried out to validate a security level of a protected hardware implementation. This approach allows us to estimate in[…] -
